Earlier, Jackson had just called her when Grace went out.
Originally Jackson called Patricia to inquire whether Nidia had a good dinner.
But Patricia said Nidia didn't go home...
Therefore, Nidia could only tell exactly where she was now.
Grace did not want to let Nidia go, but she heard Nidia's boyfriend would be here soon.
It must be Jackson...
The fact was looming that Nidia suspected her grandmother's death had something to do with Grace because of that photo, and she dropped a hint to get revenge.
Grace felt that Nidia was not targeting at her directly. She didn't care whether Nidia was trying to find out the person behind the scene, because it had little influence on her.
For the moment, she, as a minor factor, sooner or later would be of no use.
After consideration, she learned that the only way for her to get out of the mess was to make Nidia fall out of favor with Jackson...
